My Barnevelder cockerel had watery droppings which were green/white in colour, he went downhill very quickly and died overnight last night, when I last checked on him at bedtime he was panting quite heavily, we were going to get him to the vet this morning but he didn't make it. I have disinfected the coop (i did separate him from the others when he showed symptons of being unwell) I will also put stalosan down in the run, do you think this could be contagious? If so, what else can i do? All the rest of the flock seem healthy at present. x

I'm sorry Autumn

 

Putting Stalosan down can't harm.

Had he been wormed recently?

[Autumn]

Yes, he and the rest of the flock were/are regularly wormed.
